This code can be optimized further. For example, [[strength reduction]] could remove the two multiplications inside the loop (<code>6*i</code> and <code>a[i]</code>), and [[induction variable]] elimination could then elide <code>i</code> completely. Since <code>6 * i</code> must needs be in lock step with <code>i</code> itself, there is no need to have both.
